Datasheet

Bently Nevada Machinery Condition Monitoring

Description

The 3500/45 Position Monitor is a 4-channel instrument that accepts input from proximity transducers, Rotary Position Transducers (RPTs), DC Linear Variable Differential Transformers (DC LVDTs), AC Linear Variable Differential Transformers (AC LVDTs), and rotary potentiometers. The monitor conditions the input and compares the conditioned signals with user-programmable alarms.

The type of measurement and transducer input determine which I/O modules are required. See

Transducer Types for Position Measurements on page10., See Figures and Graphs on page12., and See I/O Modules for AC LVDTs and Rotary Potentimeters on page14.

You can program each channel using the 3500 Rack Configuration Software to perform the following functions:

141537 Rev. H

l Axial (thrust) Position l Differential Expansion l Standard Single Ramp Differential Expansion l Non-standard Single Ramp Differential Expansion l Dual Ramp Differential Expansion l Complementary Differential Expansion l Case Expansion l Valve Position

The monitor channels are programmed in pairs and can perform up to two of these functions at a time. For example, Channels 1 and 2 can perform one function while channels 3 and 4 may perform the same or a different function.

Page 2

3500/45 Position Monitor Datasheet 141537 Rev. H

The primary purpose of the 3500/45 Position Monitor is to provide the following:

l Machinery protection by continuously

comparing monitored parameters against configured alarm setpoints to drive alarms

l Essential machine information for

operations and maintenance personnel

Each channel, depending on configuration, typically conditions its input signal to generate various parameters called measured variables. You can establish alert setpoints for each active measured variable and danger setpoints for any two of the active measured variables.
